The following functions can be used to perform arithmetic on objects and variables.

These should be written in the following formats:

• variable.method(arguments), example - ...

• object.method(arguments), example - ...

Click each method name in the table below for more details of it, with examples.

Methods

abs

Usage:

Computes and returns an absolute value for the number specified by the parameter val.

Example:

echo abs(-123456)

echo abs(123456)

Result:

123456

123456

acos

Usage:

Computes and returns the arc cosine of the number specified in the parameter val, in radians.

Example:

Result:

asin

Usage:

Computes and returns the arc sine for the number specified in the parameter val, in radians.

Example:

Result:

atan

Usage:

Computes and returns the value, in radians, of the angle whose tangent is specified in the parameter val.

Example:

Result:

atan2

Usage:

Returns a string comprising the characters represented by the Unicode character codes in the parameters.

Example:

Result:

ceil

Usage:

Returns the ceiling of the specified number or expression. Basically this means return the number rounded up to next whole number

Example:

echo ceil(4.1)

Result:

5

cos

Usage:

Computes and returns the cosine of the specified angle in radians.

Example:

Result:

exp

Usage:

Returns the value of the base of the natural logarithm (e), to the power of the exponent specified in the parameter x.

Example:

Result:

floor

Usage:

Returns the floor of the number or expression specified in the paraenthesis... Floor is the whole number part, without the decimals. Basically means chop the decimal portion of the number off.

Example:

echo floor(1234.56)

Result:

1234

pow

Usage:

Computes and returns base to the power of pow.

Example:

Result:

max

Usage:

Evaluates val1 and val2 (or more values) and returns the largest value.

Example:

echo max( city.troop.scouter, 100k )

Result:

If city.troop.scouter (the current number of scouts in the city) < 100k, then max( city.troop.scouter, 100k ) will return the number of scouts in city. If city.troop.scouter >= 100k then it will return 100000

min

Usage:

Evaluates val1 and val2 (or more values) and returns the smallest value.

Example:

echo min(city.resource.food.amount,99999999)

Result:

this will return whichever is smaller, 99,999,999 or the current amount of food in the city

pow

Usage:

Computes and returns base to the power of pow.

Example:

Result:

random

Usage:

Returns a pseudo-random number n, where 0 <= n < 1.

Example:

echo round(random()*10)

Result:

a random number between 0 and 9

round

Usage:

Rounds the value of the parameter val up or down to the nearest integer and returns the value. Optional argument to specify precision (or number of decimal places).

Example:

echo round(6.66666666666666666666)

echo round(6.66666666666666666666,1)

echo round(6.66666666666666666666,2)

echo round(6.66666666666666666666,3)

Result:

7

6.7

6.67

6.667

sin

Usage:

Computes and returns the sine of the specified angle in radians.

Example:

Result:

sqrt

Usage:

Computes and returns the square root of the specified number.

Example:

Result:

tan

Usage:

Computes and returns the tangent of the specified angle.

Example:

Result:
